Investigation ongoing into cause of deadly NYC parking garage collapse.

Building inspectors are investigating the cause of a deadly collapse of a century-old parking garage in New York City. The collapse killed one person and injured several others. The weight of the vehicles on the roof and the age of the building are being considered as possible causes. The site remains unstable, and it will take days or weeks to clear the area. The garage's owners had yet to comply with the city's requirement for structural inspections.
